Question

6.
If one angle of a A is equal to the sum of the other two angles, then the A is
a) Equilateral & b) right angled A
b) right angled A c) scalene A d) isosceles A​

Answer 1

Answer:

In △ABC,

∠A=∠B+∠C

Now, sum of angles = 180

∠A+∠B+∠C=180

∠A+∠A=180

∠A=90

∘

Thus, △ABC, is a right angled triangle.
